Porque isto será para mim como as águas de Noé, quando jurei que as águas de Noé não mais passaria sobre a terra; assim jurei, que não me irarei contra ti, nem te repreenderei.
Il en sera pour moi comme des eaux de Noé:

Scholars' Consensus
Commentators across traditions agree that this verse anchors God’s promise of mercy in the same unbreakable certainty as the Noahic covenant. Barnes notes that God appeals to the flood oath not only because He made it, but because He kept it, and He will keep this one too. Gill explains that though God’s people are by nature children of wrath, He has not appointed them to it, saving them through Christ who bore their wrath. Matthew Henry reads the verse as a type of the covenant of grace, permanent and irreversible. Keil and Delitzsch specify that the promise refers to the converted Israel of the last days, whose Jerusalem will never be destroyed again. The shared foundation: God’s oath removes final judgment entirely; whatever temporary discipline may occur, the people will never again face the kind of devastating wrath that marked the exile.
How settled is the interpretation?
Interpretive difficulty: Medium
Main views:
- Historical-eschatological (post-exilic fulfillment): Barnes and Matthew Henry apply the promise primarily to the return from Babylon and then typologically to the church.
- Strict eschatological (end-times only): Keil & Delitzsch argue that the prophecy refers exclusively to the converted Israel of the last days, whose Jerusalem will never be destroyed again.
What is clear: God makes a covenant oath as certain as the Noahic promise, guaranteeing that His redeemed people will never face final, covenantal destruction.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| Scope of the oath | The oath guarantees that God’s people will never again face the kind of devastating, covenant-breaking wrath seen in the flood or the exile. | Some interpreters (e.g., Barnes, Matthew Henry) apply this broadly to the church throughout history; others (e.g., Keil & Delitzsch) limit it strictly to the converted Israel of the last days. |
| Meaning of 'never be angry or rebuke' | Christians across traditions agree it refers to final condemnation being removed. God’s judicial wrath is gone for the redeemed. | Catholic and Protestant traditions differ on whether this excludes all temporal punishment (purgatory) or only eternal punishment. Some Reformed theologians see it as including fatherly discipline as an expression of love, not wrath. |
| Textual variant: 'waters of Noah' vs 'days of Noah' | The variant does not change the essential comparison to the flood promise. | Keil & Delitzsch and Cambridge favor 'days of Noah' as the better reading; most English translations (WEB, KJV, ASV) follow the Masoretic 'waters of Noah.' |
| The covenant of peace (v. 10) | This guarantees the same permanence as the Noahic covenant. | Some see it as a renewal of the Mosaic covenant; others see it as a new, distinct covenant that supersedes the old. |
Historical & Cultural Context
Isaiah 54 belongs to the section of the book (chapters 40, 55) that addresses the people of Judah in Babylonian exile. Verses 7 and 8 describe God’s wrath as a “small moment” followed by “everlasting loving kindness.” Now verse 9 compares that turning point to the days of Noah. In Genesis 8:21, 9:17, God judged the whole earth with a flood, then swore with a covenant and the sign of the rainbow that such a judgment would never recur. The exile was a comparable judgment, the nation was swept away. But God now swears that the restored community will not suffer that kind of destruction again.
Several commentators (Cambridge, Keil & Delitzsch) note the textual variant “days of Noah” (כימי) instead of “waters of Noah,” connecting the phrase to Jesus’ words in Matthew 24:37, “as were the days of Noah, so will be the coming of the Son of Man.” Barnes points to the oath formula in Genesis 8:21, 22. The covenant of peace in verse 10 echoes Jeremiah 31:35, 36, where God swears by the fixed order of creation that Israel will never cease to be a nation. In the ancient Near East, an oath sworn by a deity was the most binding guarantee possible. This verse offers exactly that level of certainty.
Textual Notes
The Hebrew Masoretic Text reads “For this is like the waters of Noah to me” (כִּי מֵי נֹחַ). However, several ancient versions, including the Vulgate, Syriac, and Targum, along with some Hebrew manuscripts read “like the days of Noah” (כִּימֵי נֹחַ). The Dead Sea Scrolls of Isaiah are fragmentary at this point, but the majority of medieval codices support the “waters” reading. Keil & Delitzsch and the Cambridge Bible consider “days” the better-supported variant. The Septuagint is notably confused, translating “from the water of Noah” (ἀπὸ τοῦ ὕδατος τοῦ ἐπὶ Νῶε). The difference is minimal for interpretation: both readings compare the present promise to the flood event. The consulted sources note no other significant textual variants.
Reception History
Rabbinic tradition connected this verse to the days of the Messiah. Gill cites the Talmud (Sanhedrin 99a) as referencing Isaiah 54:9 for the messianic age. Early Christian writers such as Eusebius of Caesarea saw the verse as a prophecy of the church’s security in the new covenant. During the Reformation, this passage was used to argue for the indefectibility of God’s gracious promise, that once justified, a believer cannot fall away from grace completely. The image of a promise as sure as the rainbow has appeared in hymns of assurance, notably in “How Firm a Foundation” (lyrics such as “I’ll never, no never, no never forsake”). While the hymn’s specific source is external, the verse’s theme of unbreakable oath continues to comfort Christians facing doubts after suffering.
Preaching This Verse
Three-point outline
- God anchors the future in the past. The flood oath is the most memorable promise in Israel’s history. God says, “I did that for the whole earth; I will do this for you.”
- The oath is about final wrath, not every displeasure. Gill and Keil & Delitzsch both emphasize that God’s anger here refers to the kind of judgment that destroys a nation. Personal discipline and conviction still happen, but the ultimate verdict is settled.
- This promise rests on covenant, not mood. The Noahic covenant had a physical sign (the rainbow). The new covenant has a sealed guarantee (the cross). Both are permanent because God is unchanging.
Five-point outline
- The comparison: “This is like the waters of Noah”, the present moment of restoration mirrors that past promise.
- The oath: God “swore” (Niphal of shava). He binds Himself with the same weight as the flood covenant.
- The content: No more anger or rebuke that destroys the relationship. Barnes: “no calamities should spread over the whole church and sweep it away.”
- The guarantee: Verse 10 reinforces with mountains and hills, creation itself can shift, but God’s covenant of peace will not.
- The application: The church, like Israel, has seasons of discipline but never abandonment. The cross is God’s final oath on that.
Illustration hooks
- A parent who loses their temper with a child, then later kneels down, apologizes, and promises, “I will never reject you, even when I’m angry.” The child learns to trust the relationship, not just the mood.
- The rainbow as a universal symbol of promise: after a storm, it appears. God doesn’t need a new rainbow, He points to the one already in the sky and says, “That same promise now covers you.”
- A courtroom where a judge issues a final ruling. No appeals. No overturning. God’s oath is the closing verdict on His people’s condemnation.
Questions your congregation is asking
- “Does this mean God will never be angry with me when I sin?”
- “How does this fit with the discipline I experience as a believer?”
- “Can I lose my salvation if I keep falling into the same sin?”
Leading a Discussion
This verse marks a shift from wrath to permanent peace. God compares His promise to the flood covenant, something everyone in Israel knew had never been broken. The same God who kept that oath now swears something even more personal: “I will not be angry with you.” As you discuss, hold the tension: God does get angry at sin (the exile proves it), yet He also swears that His people will never face that kind of total destruction again. That is the shape of the gospel.
Discussion questions
- What does the comparison to the flood add to how you understand God’s promise here?
- Why does God use an oath (swear) rather than a simple statement? What does that tell you about His character?
- How do verses 7, 8 prepare for verse 9? What do they tell us about the nature of God’s wrath?
- What does the promise “I will not be angry with you nor rebuke you” mean in practical terms for a believer who still sins?
- How does the covenant of peace in verse 10 help you read verse 9? What kind of peace is this?
- Can you think of a time when you doubted God’s promise because of your circumstances? How does the flood story encourage trust?
- If God truly will never be angry with His people, how should that change the way you approach Him in prayer?

What the Commentators Say
8 public-domain commentaries, condensed into plain language.
Barnes' Notes on the Bible Protestant 1832
Barnes draws a parallel between God's covenant with Noah and His promise to the church. Just as God faithfully kept His oath never to flood the earth again, He will keep His promise to protect the church from total destruction. The church may face trials, but it will never be swept away or forsaken.
Cambridge Bible for Schools and Colleges Anglican 1880
The commentator notes a textual variant where "the waters of Noah" may be read as "the days of Noah," preferring the latter. He also observes that the mountains and hills illustrate permanence concessively: even if they move, God's covenant of peace stands firm, and the absence of an oath in Genesis is immaterial.
Geneva Bible Notes Reformed 1599
The Geneva note emphasizes that God compares His promise to Israel with His covenant with Noah. Just as He swore the flood would never again destroy the earth, He now swears He will not remain angry with Israel or rebuke them. The parallel shows the absolute certainty of God's renewed favor.
Gill's Exposition of the Bible Baptist 1748
Gill draws a direct parallel between God's covenant with Noah after the flood and His covenant with His people here. Just as God swore the floodwaters would never again destroy the earth, He has sworn not to pour out His wrath on His people. Any rebuke they receive comes not in anger but in love.
Keil & Delitzsch OT Commentary Protestant 1876
Keil-Delitzsch argue that this promise of everlasting kindness applies to the converted Israel of the last days, not the nation that rejected Christ. The prophet's view blends the near return from exile with the far final future, since the covenant still stands as an offer awaiting Israel's faith.
Lange's Commentary Reformed 1857
Lange stresses that the barren, desolate woman in this chapter is not the literal Jerusalem but the hidden spiritual kernel of Israel. When the old outward Theocracy is shattered, this latent Zion bursts forth as the mother of countless nations, finding its fulfillment in the New Testament church. He contrasts this with interpretations that limit the promise to a mere physical repopulation after the exile.
Matthew Henry's Commentary Reformed/Presbyterian 1710
Henry draws comfort from the sharp contrast between God's brief anger and His enduring kindness. Even believers espoused to God, he notes, may feel forsaken and grieve under that fear, yet their rejection is only for a moment while the mercy of the covenant is everlasting.
Wesley's Explanatory Notes Methodist/Wesleyan 1754
Wesley draws a direct parallel between God's covenant of grace and peace and the Noahic promise that the world would never again be destroyed by flood. Both are equally certain and perpetual. His distinctive note is that any divine wrath mentioned is limited: it will never reach the point of utter abandonment.
